Research on the Decolorization Adsorption Flocculation Treatment Process of Electronic Circuit Board Waste water
A large amount of metal wastewater is generated during the production process of electronic circuit boards,which can pose a threat to human health if not treated properly.This article adopts the wastewater treatment method of decolorization and adsorption flocculation to purify the wastewater generated in the electronic circuit board production industry.Study the effects of flocculant content,pH value,and treatment time on wastewater treatment efficiency.The results showed that when the pH value was 9,the mass fraction of the mixed flocculant was 0.5%,and the stirring time was 40 minutes,the decolorization rate and COD(chemical oxygen demand)removal rate were optimal,meeting the landmark emission limits in Guangdong province.
